ings, and to the letters of reference marked thereon.

Figure I `represei'its a longitudinal side elevation, Fig. II is an endview, and Fig. III a plan, of my improved machine.

Similar letters represent similar parts.

The nature of my invention consists in the combination of an elevatorwith a movable carriage or truck provided with a mechanical power-suchas a steam-engine or its equivalent-whereby either the carriage or truckmay be propelled or the elevator operated, as may be desired. l

In the accompanying drawings, A repre- -sents a carriage supported onsuitable wheels,

a. Upon this carriage or truck A a steamboiler, B, is fastened, on thetop of which a cylinder, O, is secured, acting on a horizontal shaft, D.To the forward end of the truck A the lower end of an elevator, E, isattached, provided with suitable buckets, fm., attached to a chainpassing over drums F and F and constructed in the usual manner.

Near the upper end of the elevator-frame rods G G are attached,passingbackward over the boiler and engine and connected through a rope orchain, n, with a windlass, II, attached to the end of the boiler B.

The shaft N on the forward end of the truck. A, which carries the lowerend of the elevator E, forms likewise the shaft for the lower drum, F,and is provided with cranks O on each end, which are connected throughthe rods P with corresponding cranks, Q, fast on the ends of theengine-shaft I), co1n1nunieating thereby the required motion fromtheengine to this drum F, and through the saine' to the elevator chain andbuckets m.

By the arrangement of thewindlass H with the ends of the rods G G theupper end of the elevator E can be regulated and moved in any desiredposition for the discharge of the coal.

The top of the elevator is provided with a cover, M, provided with aspout, K, to discharge the coal. To this spout K a plate, S, is fitted,capable of being turned on its center, so as to direct the discharge ofthe coal toward the one or the other side, as may be de- Sired.

The engine-shaft D may likewise be con* nected with the truck-wheels a,so as to propel the truck or carriage to any desired place where theelevator is to be used.

I claini- The arrangement of an elevator on va 1novable truck, for thepurpose of loading coal, when the saine are constructed and combined inthe manner substantially as set forth and
